ToleranceCustomer's Drawing Request
Custom ASTM A48 Class 30 gray iron parts are offered through sand casting for automotive machinery. OEM and ODM wholesale enquiries support customized sizes and tolerances defined by customer drawings. A ductile iron request is a separate material choice requiring its own complete grade specification.
Define the Class 30 component
Identify the part's function, assembly interfaces and working conditions. Keep the specified gray iron requirement tied to the component being ordered. Show the mounting and locating features that determine installation, and specify any application-specific acceptance requirements for the actual machinery duty.
Control dimensional and supply requirements
Provide the drawing revision, governing datums and permitted limits for functional features. State whether additional machining or a particular surface finish is needed for agreement during quotation. Identify the condition in which the component must meet its drawing requirements and the relationships that need to be inspected together.
Set inspection and approval records
Quality control is stated as 100% inspection under an ISO 9001 system, with ISO 9001 certification referenced. Agree the checks and records required for the selected part and establish the applicable document scope. Keep material acceptance and finished dimensional acceptance clearly connected to the order.
- State the selected gray or separately specified ductile iron grade.
- Identify quantity and initial component-approval stages.
- Define the material and inspection records required with the castings.
When requesting repeat production, identify approved changes to the drawing, material or finish so the enquiry continues to describe the same automotive machinery component.
